TL;DR: In this article, the predicted inversion between the pi2p3/2 and pi1f5/2 nuclear states in the nu(g)9/2 midshell was confirmed by using a combination of in-source laser spectroscopy and collinear laser spectrometers on the ground states of 71,73,75Cu, which measured the nuclear spin and magnetic moments.

TL;DR: The concluding result from an Ives-Stilwell-type time dilation experiment using 7Li+ ions confined at a velocity of β=v/c=0.338 in the storage ring ESR at Darmstadt is verified and interpreted within Lorentz invariance violating test theories.

TL;DR: In this article, the authors proposed a method for high-accuracy mass measurements of the shortest-lived isotopes and decay studies at the FAIR facility using an electron beam ion trap for charge breeding, ion traps for beam preparation, and a high-precision Penning trap system for mass measurements and decay analysis.

TL;DR: The neutron-rich isotopes of cadmium up to the N=82 shell closure have been investigated by high-resolution laser spectroscopy and one essential feature of the spherical shell model is unambiguously confirmed by a linear increase of the 11/2(-) quadrupole moments.

TL;DR: In this paper, the nuclear charge radius of the one-neutron halo isotope Be was determined using the technique of collinear laser spectroscopy on the $2{s} 1/2]-ensuremath{\rightarrow}2{p}{1/2,3/2}$ transition in the ${\mathrm{Be}}+}$ ion.
